Another environmental group has come out against plans for a new seven-mile long reservoir in central Indiana, citing concerns about damage to Mounds State Park.

A regional chapter of the Audubon Society says the proposed Mounds Lake Reservoir would hurt the natural environment near Anderson by flooding at least one-third of the park known for earthworks built by American Indians more than 2,000 years ago.

Chapter president Sarah McKillip tells The Herald Bulletin that the reservoir would destroy the park's nature preserve and submerge hiking trails along the White River.

An environmental study is being conducted for the 2,100-acre lake that's estimated to cost about $400 million.

Project advocates say the reservoir could boost tourism and help relieve the impact of floods and drought in the area.
